DynaSeal A premium quality floating ball valve that has proven itself in a wide variety of oilfield, chemical, petrochemical and hydrocarbon processing applications. THREADED VALVE ASSEMBLY 1/ 4 in. ( 8 mm) FULL PORT THROUGH 4 in. x 3 in. ( 100 mm x 80 mm) REDUCED PORT. WKM DynaSeal 310 Floating Ball Valves satisfy a wide range of applications. Available in a variety of standard and optional materials, in sizes from 1/ 4 in. ( 8 mm) to 4 in. x 3 in. ( 100 mm x 80 mm) and working pressures to 5000 psi. Engineered for heavy duty, maintenance free performance, the DynaSeal 310 Ball Valve is preferred for use in critical applications. SOUR OIL AND GAS SERVICE WKM DynaSeal Ball Valves are suited to applications within gathering lines, manifolds and field processing units in sour oil and gas fields. They can be trimmed to conform with NACE MR0175/ ISO 15156. Features and Benefits: DEEP RECESSED SEATS The WKM DynaSeal 310 seat is protected in a machined recess or deep pocket that surrounds and protects the seat. This design eliminates cold flow into the valve conduit and avoids potential seat damage from ball movement or flow media. TRIM 42 SEATS Seats are manufactured of filled TFE and rated to 1500 psi MOP. With working temperatures to 500° F ( 260° C) and low torque operation these seats satisfy even the most difficult of processing requirements. TRIM 43 SEATS Seats are manufactured of Acetal Plastic and rated to 3000 psi MOP and working temperatures to 220° F ( 104° C) . These seats are designed to handle the most demanding applications. These seats are designed to flex under pressure and provide a consistent range of low torque operations. They provide a full face seal against the ball and multiple seals against the top and back of the pocket to provide a positive seal. ADJUSTABLE, REPLACEABLE PACKING The in-line valve stem packing consists of PTFE impregnated graphite with an impervious metal barrier and a secondary tapered metal backup. The packing is field adjustable and never requires lubrication. The packing and the stainless steel cap can be replaced without removing the valve from the line. POSITIVELY RETAINED STEM The stem is positively retained with a shoulder. It cannot be removed with the valve in service. There are no O-rings used in this design. FLOATING BALL DESIGN DELIVERS TIGHT SEAL The ground and polished ball is free to float and mates perfectly with the conical seats for a positive, leakproof seal. Self cleaning and self adjusting, the ball is also pressure activated - the higher the line pressure, the tighter the seal. FIRE TESTED FOR SAFETY All WKM DynaSeal 310 Ball Valves are qualified under API standard 607 4th Edition. The pocketed seat and locked in stem design contributes to its excellent Fire Tested characteristics. Should the soft seats be destroyed by fire, the ball floats downstream, providing a tight metal-to-metal seal against the lip of the seat pocket. If the tailpiece seals are destroyed, the metal-to-metal tailpiece to body connection retards external leakage. INDICATOR HANDLE The design of the handle permits installation on the stem in the correct position only, in alignment with the ball port. When the handle is aligned with the pipe, the valve is open. When the handle is perpendicular to the pipe, the valve is closed. LOCKING DEVICES Locking devices are standard on all 4 in. x 3 in. ( 100 mm x 80 mm) and smaller manually operated valves and permit locking in either the open or closed positions. STANDARDS AND SPECIFICATIONS Sizes: • 1/ 4 in. ( 8 mm) Full Port • 1/ 2 in.

There are hundreds of applications in such plants where WKM DynaSeal 310 Ball Valves are providing efficient service. REFINING The many metal seats, seals and available trims offer the versatility needed to handle the wide variety of products used in the refining process. TEFLON BODY SEAL A Teflon body seal is used between the valve body and tailpiece. DEEP RECESSED SEATS The seat is recessed into a deep machined pocket, which serves to surround and protect the seat on all sides. This design eliminates cold flow into the valve conduit where it can be damaged by the action of the ball or the flow medium. The result is extremely long service life. ADJUSTABLE, REPLACEABLE PACKING The in-line valve stem packing through ASME Class 300 consists of PTFE impregnated graphite with an impervious metal barrier. The packing is field adjustable and never requires lubrication. The packing and the stainless steel cap can be replaced without removing the valve from line.

POSITIVELY RETAINED STEM The stem is positively retained and cannot be removed with the valve in service. INDICATOR HANDLE The design of the handle ASME Class 300 permits installation on the stem in the correct position only, in alignment with the ball port. When the handle is aligned with the pipe, the valve is open. When the handle is perpendicular to the pipe, the valve is closed. FLOATING BALL DESIGN DELIVERS TIGHT SEAL The ground and polished ball is free to float and mates perfectly with the conical seats for a positive, leakproof seal. Self cleaning and self adjusting, the ball is also pressure activated. The higher the line pressure, the tighter the seal.
